Camera rotation using 'Q' and 'E' keys.

Garling · August 1, 2014, 7:55pm

I am working in a Top Down template, I want to be able to use the ‘Q’ key to rotate the camera counter-clockwise and ‘E’ clockwise around player. I have been looking but can not find exactly what I am looking for.

axelZellalex · August 1, 2014, 8:42pm

weird i implemented this last night
so i just set up an event in the Input menu of my project called Camera Rotation under Axis Mapping, set Q and E to be 1 and -1 (or the other way round cant remember)
then pending on your setup you want to move the Camera or Spring Arms world rotation

so in my Controller blueprint I have :

Get Player Character -> Cast To My Character -> Get Spring Arm - Set WorldLocation(newRotation)

Get Spring Arm -> Get World Rotation -> Break Rot (Pitch, Yaw, Roll)

Scale from my axis mapping is then added to the value of the Yaw then I do :

newRotation = Make Rot(Pitch, Yaw + Scale, Roll)

hope this helps!

Can you post a screen shot please?

axelZellalex · August 2, 2014, 3:36pm

yeah of course, this is the only bit of blueprints i dont like, where as with code you can just copy n paste, with BP’s you have to take a screen shot. i know i can copy n paste the code in here, but i think unreal 4 gets upset if its referencing variables you dont have ?
ah screw it, screen shot and code (cut n paste into your Controller)

You can also do something like this. The “RotateCamera” timeline is just a float track that goes from 0 to 360, and has loop enabled. You don’t need the “Relative Rotation” and “Break Rot” nodes, I’m only getting the pitch so it doesn’t screw with my other camera controls.

Garling · August 6, 2014, 6:08pm

@axelZellalex Tried and will not work, I needed to add the MyCharacter var to it.

axelZellalex · August 6, 2014, 6:32pm

hey Garling , yea you will that is literally my MyCharacter class
as i said, you cant just copy the BP stuff
just do a Get My Character

Garling · August 6, 2014, 6:44pm

@Tekoppar I do not see the rotate camera timeline function.

Tekoppar · August 7, 2014, 6:22am

It’s just a timeline function with a float track that goes from a value of 0 at 0 seconds to a value of 360 at 5 seconds and has loop enabled.

Thanks a lot @Tekoppar , I’m working on the Top Down template and have been searching for a method for input based camera rotation. Yours work perfectly.
